Application filed September 6, 1918. Serial No. 252,913.

Be it known that I OLIVER W. MOJON- NIER, a citizen of the United States, residing at Oak Park, in the county of Cook, State of Illinois, have invented certain new and useful Improvements in Can-Polishing Machines; and I do hereby declare the following to be a full,'clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to 'a can polishing machine and more particularly-to the class of automatic can polishing machines.

The primary object of the invention is, the provision of a machine of this character wherein the ends of cans for containing evaporated milk, tomatoes, corn, other veg- I etables or substances, will be polished under the action :of brushes, which are arranged to work against-the ends of the cans in parallel relation to each other transversely of the path of travel of the cans, which are :moved by an endless conveyer traveling upon a track which is inclined from the receiving 'end to the delivery end of the machine, the brushes being prevented from catching between the cans when in motion and in the 1 links of the conveyer.

Another object .of provision of a machine of this character,

wherein the use of'elevating mechanism at,

both receiving and delivering ends of the machine are eliminated ordispensed with,

the brushes for the polishing of the ends 7 of the cans being operated by the up and down stroke and in parallelismrwith each other. thereby enabling the brushes to act freelyand uniformly upon" the ends of the I motion, thereby avoiding any derangement of thecans in the travel ofthe same through the machine.

cans without subjecting the same to any lost A further object of the invention is, the

provision of a machine of this character,

wherein the brushes are readilyadjusted to accommodate.therebetween different sizes of cans which arexcontinuously fed by an endless conveyer the same being of novel form to assure the proper feeding ofthe cans and to avoid excessive power in the operation 3 Atstill further object of the invention, is

the invention is, the' pended.

In the accompanying drawing: gure 1, s a s1de elevatlon'ofa can po'llshlng machine constructed in accordance with the invention, the feed chute being shown in vertical section and a portion of the machine being broken away for illustrating the details.

Fig. 2, is a front end elevation of the machine. r

Fig. 3, is a rear end elevation thereof.

Flg. 1, is a fragmentary enlarged vertical transverse sectional view.

Fig. 5, is a fragmentary detailed side elevation of the guide wheel for the conveyer. Fig. 6, is a view similar to Fig. 5, showing the power or driving wheel for the .con-

veyer.

Fig. 7, is a fragmentary vertical longitudinal sectional viewthrough the machine. Fig. 8, is a detailed fragmentary transverse sectional view showing one of the brushes and its operating stem.

Fig. 9, is an outer endelevation thereof.

Fig. 10, isian enlarged longitudinal sectional view through the chain or conveyer.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawing in detail, A, designates generally, the main supporting frame of the machine, which includes the base 10 from the front end of which 'rise short vertical posts 11, while at the rear end rise long vertical posts 12. The upper ends of the posts 11 and 12 carry inclined side sills 13, to which are connected at intervals cross sills or track supports 14 bolted or otherwise fastened thereto. Mounted thereon longitudinally of the frame centrally of the same, is the inclined conveyer track or runway 15 which extends from one end to the other of the frame. Fixed to the posts 11 and 12 beneath and in spaced parally thereof bearings 17 in which is journaled a driven shaft 18 disposed transversely of the frame, and this shaft supports a drive belt wheel 19 over which is trained an endless driving belt chain 20 the same also being trained over a driving belt wheel 21 on the driving shaft 22 of a motor 23 preferably of the electric type, mounted and supported upon the base 10 in any suitable manner. 7

Arranged between the supplemental side sills 16 at intervals are cross struts or braces .fixed to the driven shaft 18 so thatmotion from the latter will be imparted to the countershaft 26 which carries and has fixed thereto a driving wheel 30 preferably of octagonal shape having chain teeth 31 for meshing engagement with the links of an endless conveyer,hereinafter fully described.

At the lower end of the receiving end of the frame A, and'suitably journaled in the short post 11 is a horizontal shaft 32 on which is arranged a guide wheel 33, preferably octagonal shape for the endless conveyer, while the driven shaft 18 has thereon an idle wheel 34 forsaid conveyer.

The endless conveyer comprises a flexible chain having a series of solid links 35 pivoted together at 36 and each link is formed with a recess 37 opening through the inner face thereof, to receive the teeth 31 of the drive wheel 30 and the upper stretch of this chain 35 travels upon the track; '15 while the lower stretch of said chain travels over the idle wheels 34, the links 35 of the chain being formed with cam abutments, cleats or flights 38 having concavities 39 for receiving the can to be conveyed through the machine. The width of the conveyer is less than the length of the smallest size can to be introduced into the 'machine for exposing the ends of the cans beyond the track at each side thereof for action thereon by the brushes, hereinafter fully described.

Mounted on the frame and adapted to fully polished and are subsequently debridge the track 15 are arch members or bridge yokes 40. Supported directly over the track 15 of the conveyer, movable thereon is a retaining plank or guide 41, which overhangs the cleats or flights 38 on the upper stretches of the chain 35 to retain the cans in the conveyer when being hoisted thereby upon the track 15 from the low to the high end of the machine.

At the lower or receiving end of the frame ,7 machine comprises spaced pairs of reciproeating brush standards 44 arranged in parallel relation to each other and are slidable in guide brackets 45 fixed to the inner sides of the sills 13 and 16 and the lower endsfof these standards 44 are loosely connected through the medium of links 46 with the outer ends of rockers 47. The inner ends of the latter are pivoted at 48 to arms 49 eccentrically pivoted to wheels or disks 50 fixed to the driven shaft 18 at the ends thereof, so that the rockers 47 will be actuated for the reciprocation of the brush standards 44 for actuating the brushes herein described.

Adjustably mounted in the upperends' of the standards 44 arethe threaded stems of eye bolts 51 in whose eyes are engaged brush 7 supports each including a threaded shank 'of cans between the opposed brushes in the machine for the polishing of the ends of said cans byreciprocal action of the brushes in their parallel movement up and down in the machine. 7

In the operation of the machine the cans are fed on the conveyer to the supply chute 42 which carries said cans upwardly of the track 15 from the lowto the high end of the machine. The cans travel between the brushes 55 which reciprocate in parallel relation with each other on, up. and down movement thereof to act upon the ends of the cans for the polishing thereof, and said brushes will not become caught in the links of the chain conveyer nor will they project between the cans on the conveyer.

On the travel of the cans they are successlivered from the delivery chute 43 to a suitable point of deposit. It is apparent that the brushes can be renewed when the occa- 'sion requires and the necessity. of elevating meansat the receiving and deliveryends of the machine is avoided. The can ends will be thoroughly polished by the action of the brushes prior to the discharge thereof from the machine. V r

From the fore oing it is thought, that the construction an the manner of operation of the machine will be clearl understood and therefore a more extends explanation has been omitted. It is, however, to be understood that the applicant reserves the right to make changes, variations and modifications not in the invention such as come within the bounds of the appended claim without deviating or departing from the spirit of the invention or sacrificing any of its advantages.

What is claimed is:

In a can polishing machine, the combination with a supporting frame having an inclined track, can conveying mechanism movable over the track, and upright uides in the frame; of standards mounted or vertical reciprocation in said guides at opposite sides of the track, eye bolts whose stems are adjustable vertically in the upper ends of the standards, threaded shanks assing horizontally through the eyes of said bolts, nuts on the shanks at opposite sides of such eyes, brush stocks carried by said shanks and facing toward the ends of the cans, and driving means for moving the conveying mechanism and simultaneously reciprocating said standards.

In testimony whereof I afiix my signature, in the presence of two witnesses.

OLIVER W. MOJONNIER.
